LATCH.

Substitute for application Serial No. 702,301, filed March 27, 1924, abandoned March 18, 1926. This application filed Iiay 13,

This invention relates generally to latch locks, having more particular reference to a latch lock comprising a sliding bolt which is retained in engagement with its keeper by hasp and staple elements to which padlocks are adapted to bev applied, the invention having for an( object the provision ot a novel and improved latch lock ot this type. This application is a substitute application or" one tiled by me on March 27, 1924 under Serial No. 702,301.

For further comprehension ot the invention, and ot the object and advantages thereot, reference will be had tothe following description and accompanying drawing, and to the appended claims in which the various novel :t'eatures ot the invention are more particularly set forth.

Fig. 1, ot' the drawing is a tace view showing my improved latch lock applied to a door.

Fig. 2, is a horiz'ontal sectional view' taken on the line 2-2 of Fig.l 1.

F 3, is a transverse sectional view taken on the line 3 3 ot Fig. 1.

Fig. 4, is a fragmentary horizontal sectional View taken on the line 44 oi Fig. l.

Fig. 5, is an underside plan view ot the rear end of the bolt.

Referring now to the drawing, the reterence numerals and 11 indicate portions ot a door and door trame respectively, which are secured to the bolt guide and the bolt keeper. rllhe bolt guide, comprises the plate 12, on which the angular guide members 13 are formed, this plate being, secured to the door by any suitable tastening elements such as indicated at 14. Slidably mounted on the plate 12, and comin-ed between the guide elements 13, is a block 16 which .is termed with the lateral ribs or projections 17, which engage the said guide elements 13. rlhis block is also formed with a longitudinal boring in which is rotatably engaged the bolt 20. The keeper on the door trame comprises the plate 21 secured by the fastening elements 22 to the. said trame and having a projection 23 thereon formed with a longitudinal boring 24 to receive the end ot the bolt which projects beyond the block 16.

Fixed to, and projecting laterally from, the bolt 20, at the point where the latter emerges from the block 16, is an arm 25 which has mounted on its tree end a hasp 1926. Serial No. 168,713.

plate 26 which projects across the edgesot1 the door and the trame and is formed 'with a number of transverse slots to receive staple elements carried respectively by the door and the frame, there being a pair ot end slots 28 and a central slot 29 ot the staple elements there is a pair 30 arranged to engage in the slots 28 at the ends ot the plate 26 and a second pair 31 which are closely adjacent one another when the door is closed and which are adapted to'engage in the slot 29 at the` center ot the said plate, the respective staples of each pair being mounted one on the door and the other on the trame, being here shown as fixed to angular brackets 32 and 33. As shown the staples 31 may be flattened on their adjacent sides Yto liein close contact with one another and term in effect a compound staple, A handle 35 is'provided on the end of the arm 25 to facilitate swinging movement ot the plate 26 v'on the bolt 20. Forward movement ot' the bolt may be limited by means of a pin, 37' on the underside of the block which engages in a longitudinal slot 38 in the base plate 12, while rearward movement of the bolt may be limited by means of an up turned lug` 39 on thee-nd of the said base plate. To release or apply the bolt the latter is moved longitudinally, and the hasp plate swing to or from engaging position with the staples 80, 31. j

To prevent accidental damage to the bolt by swinging the door to closed position with the bolt projected to its forward position l1 provide a novel retaining element which holds the bolt .in retracted position. As here shown a bayonet recess 42 is formed on the une erside ot a head 43 on the rear end ot' the bolt which cti-operates with the arm 25 in retaining the bolt against longitudinal movenientin the block 16. This recess coin municates on one side with the rear end oi" said head and its lateral arm is formed with an inclined wall 42 which is adapted to cooperate with a pin'44 tiXed in the plate 12 and projecting thereinto to insure ot the bolt being drawn backward to its fullest ex*- tent when the handle 35 is released. Surrounding tlie bolt, adjacent the head 48 thereon, is a spring 46 which is iixed at one end ot the bolt and at its opposite end to the plate 12 and which normally urges the bolt in a rotary direction to swing the baspplate 26 downward. vWhen the bolt is movedbaclii'ard the pin enters the recess l2 and ivlien the handle is released tlie' bolt turns, under the iniiuence oi' the spring 46, the pin 44; entering the lateral, arn'i ot the recess and locking the bolt in its rearward position.

l'ith njiy improved bolt a combination bolt and padlock arrangement is provided, While the door can be locked in a' position' slightly open by arranging the partswvitli an end slot in the h'a'sp plate 2G engagetlwitli the section of the interniediate staple 3l, which is mounted on the dooi ,f ijzn'n'e. 4'

`Wliile l' have illustrated and des preferred embodiment in'y invention it" is to be understoodthat' do not limit selto the precise I Vconstruction` he ,ein sh'oivn, and that various changes and niodilin p cations might be made therein `Without de'- partin'g from the epirit and `scopev ofthe invention as delined in the a'p'pendedclaiins.

Having;l thus deeciib'ed invention. what claini as` new and deire to protect' by LettersA Patent ot the United States, is as' follows :f y

l. i latch comprising a bolt, a l'e'pei" therefor, block in `which" said' vbolt is ro tatably mounted, a guide Aelement tor ysaid block permit-ting longitudinal niovein of the latter with thebolt, an arin projecting" laterally troni the bolt', a hasp plate tilted to the free end of said arni and fori'ned ivitl'i a plurality ot' slots, said slots' being spaced troni one another longitudinally. of the bolt, and' extending transversely ivith re'sfpel'i'ctlto the' latter', and vstaple elements vadapted for inounting respectively on a' door and 'lra'nie and adapted` to individually the respective 'slots' on the liasp plate; v

A latch` comprising a"bo`lt a` keeper therefor, a blocl in which said bolt isf ro@` tatably mounted, a guilde element for said block perin itting' ylinge,"itiidinal l nioveiiient of the latter ivith the bolt, an arm" projecting laterally troni thefbolt, elongated lii'sp plate iiiedvto the re'e end of said Aarinand formed with a plurality of slots', said plate' etending' parallel to bolt, and staple elenients' adapted for. nio'unting respectively on a" door and door traine, and adapted to individually engage the respective slots on the said hasp plate said plate having a slotiiear each end and a central slot said central slot being adapted to receive a compound staple element having one part orined on tlie door andV thel other on the door 'i1-aine.
